Water Detection Probe Systems

Download Water Probe PDF Brochure


Water Detection Probe Systems detect the presence of water in a filter-separator sump by utilizing a conductivity probe attached to the vessel and an intrinsically safe relay to control fuel flow by stopping a pump or closing a valve.


Full Functional Test Feature:
Allows water to be introduced into the probe assembly without introducing water into the vessel sump or the fuel stream. This is not an indirect test of the inside of the probe or an electrical test of the relay - the probe is tested under the same conditions as which it will operate.
